The stars were out in Vegas for the Mayweather-Pacquiao fight Saturday night and the highly-touted event lived up to the drama, with the two boxers going all 12 rounds before Floyd "Money" Mayweather won in a unanimous decision.

2. THE DARK KNIGHTS
Forget about "Pac-Man", there were three Batmen in the building! Ben Affleck, Christian Bale, and Michael Keaton, who have all portrayed the DC Dark Knight, were in attendance at the fight. There were rumors that George Clooney was also in Vegas for the event, but no sightings of the star, leading some internet jokesters to speculate on an Ocean's 11-style heist.

3. DOUBLE DUTY
Several celebs, including New England Patriots players Tom Brady and Rob Gronkowski, made a day of attending the Kentucky Derby on Saturday afternoon and the Mayweather-Pacquiao showdown at night. With heated NBA and NHL playoff games and the NFL Draft also being held, Saturday was quite a day in the world of sports!

Not surprisingly, Justin Bieber was in Mayweather’s posse on fight night, walking behind the the boxer as he walked out to the ring. What was surprising was Bieber’s choice of attire for the evening. The pop star looked classy in a suit, a contrast to Jimmy Kimmel’s Run DMC-inspired outfit as he followed Manny Pacquiao.

5. THE RESULT
Early rounds went back and forth between the two fighters, but Floyd Mayweather fairly dominated the fight from the first jab, landing more punches in nearly every round and rarely looking threatened by Pacquiao. The commentators and unofficial judges had "Money" ahead the whole time, and the official judges agreed, awarding him the win in a unanimous decision.

Though he taunted the Pacquiao-friendly crowd before and after his win was announced, Mayweather had nothing but compliments for his opponent in his post-fight interview, calling him a "tough competitor" and a "true champion at heart."

6. THE MONEY
Mayweather walked away with far more than a title after his 48th career victory, so it's not surprising that the fighter thanked his sponsors in his post-game interview. The boxer stood to potentially earn $180 million from the fight Saturday, or roughly $83,000 per second, more than most top-caliber pro athletes will earn in their entire career.

7. WHAT'S NEXT
Mayweather has one more fight left on his contract with CBS and Showtime, after which, the boxer reinforced in his post-game interview, he plans to "hang it up," ideally with a record of 49-0. Of this long-awaited fight, Mayweather said simply, "When the history books are written, it was worth the wait."
